12 requirements for the care and maintenance of metallographic microscopes
As an instrument, metallographic microscope should pay attention to the maintenance of microscope related details during use. It not only protects the metallographic microscope, but also greatly helps to stabilize its operation. We all know that microscopes play an important role in production and scientific research work. In long-term working environments, microscopes may cause some small problems and abnormal operation. This requires us to carefully maintain microscopes every day and standardize their operation.
1. The laboratory should have three protective conditions: earthquake resistance (away from the earthquake source), moisture resistance (using air conditioning and dryers), and dust prevention (covering the ground with flooring); Power supply: 220V ± 10%, 50HZ; Temperature: 0 ° C-40 ° C.
2. When focusing, be careful not to let the objective lens touch the sample to avoid scratching the objective lens.
3. Do not switch the objective lens when the center of the circular hole on the stage pad is far away from the center of the objective lens, in order to avoid scratching the objective lens.
4. When adjusting brightness, it is important to avoid sudden changes in brightness or excessive brightness, as it can affect the lifespan of the light bulb and also damage vision.
5. All (function) switching should be done lightly and accurately.
When shutting down, adjust the brightness to * low.
7. Non professionals should not adjust the lighting system (filament position lamp) to avoid affecting the imaging quality.
8. When replacing halogen lamps, pay attention to high temperatures to avoid burns; Be careful not to directly touch the glass body of the halogen lamp with your hands.
When not in use, adjust the objective lens to the * low state through the focusing mechanism.
10. When not in use, do not immediately cover the dust cover. Wait for it to cool down before covering, and pay attention to fire prevention.
11. Place infrequently used optical components in a drying dish.
12. Non professionals should not attempt to wipe the objective lens and other optical components. The eyepiece can be wiped with a degreased cotton swab dipped in a 3:7 ratio (anhydrous alcohol: ether) mixed liquid and shaken dry. Do not use other liquids to avoid damaging the eyepiece.
The maintenance and upkeep of microscopes should pay attention to the above 12 requirements, which are of great help for the maintenance and upkeep of microscopes, effectively extending their service life, saving costs, and improving work efficiency.
